What Changed
Pennymac set its conforming loan limit at $850,000 for one-unit properties, while UWM raised its cap to $847,440 ahead of the official FHFA update expected later this quarter. This represents a $60,560 to $63,120 increase from the 2024 baseline of $766,550. Loans above these thresholds now carry jumbo pricing, carrying rate premiums of 25 to 75 basis points depending on credit profile and loan-to-value ratio.
The Numbers That Matter
| Loan Amount | Conforming Rate (Est.) | Jumbo Rate (Est.) | Monthly Payment Difference | 30-Year Cost Difference |
|---|---|---|---|---|
| $766,550 | 6.25% | 6.25% | $0 | $0 |
| $850,000 | 6.25% | 6.75% | $270 | $97,200 |
| $1,000,000 | N/A | 6.75% | $513 vs conforming baseline | $184,680 |
| $1,500,000 | N/A | 7.00% | $946 vs conforming baseline | $340,560 |
Rates assume 740+ FICO, 20% down, and current market conditions. Jumbo premiums widen at loan-to-value ratios above 80% and narrow below 70%.
What This Means for Your Portfolio
A $1,000,000 loan now costs $513 per month higher than it would have under conforming terms at the prior limit. Over 30 years, that is $184,680 in additional interest expense. For a $1,500,000 loan at a 7.00% jumbo rate versus a hypothetical 6.25% conforming rate, the delta is $340,560 over the life of the loan. Buyers financing between $850,000 and $1,000,000 face the steepest marginal cost increase relative to the conforming baseline.
Scenario Analysis
| Property Value | Loan Amount (80% LTV) | Rate Type | Estimated Rate | Monthly P&I | 5-Year Interest Paid |
|---|---|---|---|---|---|
| $1,062,500 | $850,000 | Conforming | 6.25% | $5,233 | $263,450 |
| $1,250,000 | $1,000,000 | Jumbo | 6.75% | $6,489 | $335,200 |
| $1,875,000 | $1,500,000 | Jumbo | 7.00% | $9,980 | $522,100 |
All scenarios assume 20% down, 740+ credit score, and zero points paid at closing. Jumbo loans under $1,000,000 may qualify for portfolio pricing at select lenders, narrowing the spread by 10 to 15 basis points.
Mortgage Strategy Implications
Buyers financing just above the conforming limit face trade-offs in down payment size versus rate cost. A $900,000 loan at 6.75% costs $5,839 per month. Increasing the down payment by $50,000 to bring the loan to $850,000 at 6.25% results in a monthly payment of $5,233, a difference of $606 monthly and $218,160 over 30 years. For purchases between $1,062,500 and $1,250,000, the marginal cost of jumbo financing is $1,256 per month compared to the conforming baseline.
Refinance candidates currently holding jumbo loans above $850,000 will not qualify for conforming pricing unless their loan balance has paid down below the new limit. A borrower with a $900,000 balance and a 7.25% rate could save $418 per month by refinancing to a 6.75% jumbo rate, compared to $688 per month in savings if they paid the balance down to $850,000 and accessed conforming pricing at 6.25%. The break-even point on a $50,000 principal prepayment to capture the conforming rate is 74 months, assuming the borrower holds the loan to term.
Lenders may adjust their portfolio loan thresholds in response to the FHFA update. Borrowers should compare conforming, jumbo, and portfolio pricing across multiple institutions before locking a rate. Compare options across at least three lenders to identify the best fit for your credit profile and loan-to-value ratio.
Frequently Asked Questions
Q: Does this limit apply to all U.S. counties?
A: No. High-cost counties receive limits up to 150% of the baseline, potentially reaching $1,275,000 in markets like San Francisco and New York.
Q: What happens if the FHFA sets a different limit than Pennymac or UWM?
A: Lenders will adjust retroactively. Loans locked under the early limits may reprice if the final FHFA figure comes in lower.
Q: Can I buy down a jumbo rate to match conforming pricing?
A: Rarely. A 50-basis-point buydown on a $1,000,000 loan costs approximately $10,000 in points upfront, recoverable only after 20 months at the lower payment.
Q: Does this change the deductibility of mortgage interest?
A: No. The $750,000 mortgage interest deduction cap remains unchanged. Only interest on the first $750,000 of acquisition debt qualifies for the deduction.
